Biphenyl and diphenyl
WebBiphenyl is a colourless to yellow solid with a pleasant odour. It is soluble in alcohol, ether, benzene, methanol, carbon tetrachloride, carbon disulfide, and most organic solvents. It is very slightly soluble in water. Formula mass: 154.21. Melting Point: 70°C. WebA proof-of-concept liquid phase sulfur recovery process was explored in a eutectic solvent of biphenyl and diphenyl ether. Sulfur conversions up to 99.96% could be achieved within the solvent over commercial alumina and titania catalyst for a simulated tail-gas feed containing up to 5% sulfur species. A temperature range of 120 to 150 °C was explored to take …
